Specific embodiment
Below in conjunction with the embodiment of the present invention and attached drawing, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
As shown in Figure 1-3, the stage apparatus of the Shield tunnel secondary grouting includes slip casting paralell 1, bottom walking
2, lateral support wheel 3, skirting board 4, coating steel pipe railing 5, water butt 6, ladder 7 are taken turns, behind the bottom of the slip casting paralell 1
End two sides are separately installed with a bottom traveling wheel 2, fix on the bracket and slip casting paralell 1 of one of bottom traveling wheel 2
Ladder 7 is installed, water butt 6 is mounted on the bottom of slip casting paralell 1, and the diameter of water butt 6 is 600mm, and being equipped with water butt 6 has
Effect avoids the in disorder phenomenon of work surface pipeline.The lower front of slip casting paralell 1 is equipped with the lateral branch being obliquely installed
Support wheel 3, two bottom traveling wheels 2 are triangularly arranged with a lateral support wheel 3, and tilting moment is 0, is greatly improved
The safety of operating environment.1 top rear of slip casting paralell is equipped with coating steel pipe railing 5 and skirting board 4, and skirting board 4
In the lower part of coating steel pipe railing 5, during slip casting, place can be kicked by the cement slurry of 4 sole of skirting board.
The slip casting paralell 1 uses the H profile steel welding production of HW150 × 150mm.
The bottom traveling wheel 2 is the concave steel wheel that diameter is 350mm.
The lateral support wheel 3 is the rigid plastics wheel that diameter is 150mm.
Installation method of the invention is as follows:
1) production of slip casting paralell 1 processing: slip casting paralell 1 uses the H profile steel welding production of HW150 × 150mm, first to each group
Cutting stock is carried out at component, then the welding of each H profile steel component is integral, finally checkered steel plate is welded on paralell 1.
2) bottom traveling wheel 2 is processed: the concave that the bottom traveling wheel 2 on secondary grouting paralell 1 is 350mm using diameter
The steel plate of steel wheel, the H profile steel of HW150 × 150mm and 20mm thickness makes, and 20mm thick steel plate is cut into having a size of 180mm × 390mm
Rectangle (4), H profile steel Cutting Length 520mm(2 part), recombinant weld integral (2).
3) lateral support wheel 3 is processed: the rigid plastics wheel and 20mm thick steel plate that lateral support wheel 3 is 150mm using diameter
Production, it is respectively 390mm × 100mm that 20mm thick steel plate, which is cut into size, and each one, the rectangle of 230mm × 100mm, and bottom
The upper bottom 120mm of 230mm, the right-angled trapezium of high 80mm one, recombinant welding are integral.
4) each component of machine-shaping is transported to the tail portion of mating trailer after shield machine using battery truck in hole, uses trailer
Sunpender combination chain block on the tailstock of tail portion is lifted, installation site as needed, temporarily by 1 spot welding of slip casting paralell
It is temporarily fixed in the tail portion of trailer, then carries out the two bottom traveling wheels 2 and a lateral support wheel 3 of 1 bottom of slip casting paralell
Welding unclamp again tailstock after bottom traveling wheel 2 and lateral support wheel 3 are welded according to track and section of jurisdiction intrados position
Sunpender and chain block, finally install 1 bottom of slip casting paralell water butt 6 and welding 1 upper height of slip casting paralell be
The coating steel pipe railing 5 of 1.2m high and the small ladder 7 of tail portion.
The working principle of the invention:
Orbit Matching in two bottom traveling wheels 2 and tunnel, lateral support wheel 3 is contacted with the side wall of tunnel, with two bottoms
Traveling wheel 2 forms triangle load-carrying members, guarantees the stability of entire stage apparatus, to also ensure that slip casting paralell 1 guarantees
In the state of relative level, at work, staff can carry out secondary grouting work on slip casting paralell 1.
It is usually small in subway tunnel and the lesser tunnel of some sections, the more spaces of shield inboard installation.Secondary grouting is usual
Using single fluid grouting machine or double-fluid grouting machine, while secondary grouting need to usually carry out mixing, i.e. secondary grouting inside shield machine
Equipment, material need biggish slip casting space to realize, generate contradiction with the small space of shield machine.For this purpose, the present invention is main
It connect to form individual slip casting trolley with shield machine by rear mating carriage track, it is mobile simultaneously during shield machine driving
Realize that secondary grouting follows up in time.
Use of the invention improves the utilization of small space in hole, reduces the security risk of operation in hole；Reduce
Interference of other operations to secondary grouting operation, improves construction efficiency in hole, accelerates shield-tunneling construction progress, saves a large amount of
Duration；Eliminate the later period construct exclusively for secondary grouting and the operation platform set up, reduce artificial, material investment, save
Cost.
The invention enables secondary grouting working spaces and exit passageway in hole to separate, and makes full use of narrow in Shield tunnel
Space reduces interference of other operations in hole to secondary grouting operation；Operation in a safe and reliable hole is provided simultaneously
Environment ensure that the safety construction image in Shield tunnel；Mating trailer after shield machine can be followed to go ahead together, no
The reuse that mating carriage track, sleeper are removed after influence shield machine.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although by upper
It states preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be in form
Various changes are made to it in upper and details, without departing from claims of the present invention limited range.
